Recent industry recognition highlights Internap’s technology leadership in Georgia

ATLANTA ─ Sept. 21, 2011 ─ Internap Network Services Corporation (NASDAQ: INAP), a provider of intelligent IT Infrastructure services, announced a relocation of its corporate headquarters from downtown Atlanta to One Ravinia Drive in the Perimeter region of metro-Atlanta that will take place in the first quarter of 2012. The headquarters move is prompted by Internap’s planned Atlanta data center expansion, as announced in July. The relocation of the current headquarters from 250 Williams Street will open up 31,000 additional net-sellable square feet of data center capacity at that facility to serve the demands of the nation’s fourth largest concentration of Fortune 500 companies. When the expansion is fully deployed, Internap’s total Atlanta data center footprint will position the company as one of the top five retail colocation providers in the metro-Atlanta area.

The relocation to a state-of-the-art Perimeter-area facility is another indication of Internap’s execution of strategic growth, building on the more than 50 new hires this year already, half of which are located in the Atlanta area, and highlighting its firm commitment to employees. With several new engineering and operations opportunities currently available with Internap both in the Atlanta region and beyond, the new location is centrally located to improve the commute time for many existing employees and to attract Atlanta’s top-caliber high-tech talent.

Recent industry recognition further highlights Internap’s technology leadership in Georgia. Earlier this year, Internap was recognized for its contribution to advancing Georgia’s technology sector by the Technology Association of Georgia (TAG) as a “Top 40 Innovative Technology Company,” and, just this month, Internap was ranked as No. 68 on Georgia Trend magazine’s list of “Top 100 Public Companies.”

“Internap’s move to a new corporate headquarters will allow us to support employee growth and address the increasing demand for intelligent IT Infrastructure services,” said Eric Cooney, chief executive officer of Internap. “Building on the market leadership we’ve established delivering premium data center services, Internap is well-positioned to leverage the momentum created by the evolving digital economy.”
